不同吸痰方法防止脑卒中机械通气患者食物反流的效果比较

目的比较两种吸痰方法防止脑卒中机械通气患者食物反流的效果。方法选取26例脑卒中机械通气患者为研究对象，采取自身对照法，单日采用试验吸痰法，双日采用常规吸痰法，比较两种方法食物反流次数。结果试验吸痰法的反流率为7．0％，低于常规吸痰法的反流率13．7％，差异有统计学意义（x2=11．24，P〈0．05）。结论对于脑卒中机械通气患者采用试验吸痰法可以减少食物的反流率，从而减少吸人性肺炎的发生，有利于患者的康复。

Comparison of two different ways of sputum aspiration for food reflux in stroke patients with mechanical ventilation

Objective To comparison the effect of two different ways of sputum aspiration for food reflux in stroke patients with mechanical ventilation.Methods Experimental sputum aspiration method and conventional sputum aspiration method were applied in 26 stroke patients with mechanical ventilation to conduct the self-control study.Two different ways of sputum aspiration for food reflux were compared ( experimental sputum aspiration in odd numbered days VS routine sputum aspiration in even numbered days).Results There were significantly differences in food reflux rate with two ways: experimental sputum aspiration method was 7.0％,and another was 13.7％(x2 =11.24,P＜0.05).Conclusions Experimental sputum aspiration method applied in stroke patients with mechanical ventilation can reduce food reflux rate,thereby reduce the incidence of aspiration pneumonia and was beneficial for the rehabilitation of patients.
